NSUrl swift 2 with greek and other special characters

I'm trying to make a server request with

NSUrl(string: "http://example.com/α")


In which
α
is a greek character. So when i request this i get an error and my app crashes. So i tried to encode the url to this

let myUrl = NSURL(string: myLink.stringByAddingPercentEscapesUsingEncoding(NSUTF8StringEncoding)!)!


and now my link has become
http://example.com/%CE%B1


where
%CE%B1
is the
α
character. Although my server does not recognise it and it doesnt send me back the data.
I use node.js with io.socket connections. Is there any way with
swift
to send the correct url without the percent encoding?

Answer

For encode α in your url

let str = "α"
let url = str.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLQueryAllowedCharacterSet())

Now decode url string like this

let orgStr = url?.stringByRemovingPercentEncoding
print(orgStr)
